Norway Sterling Green & Brown Enamel Butterfly Pin

This unusually colored butterfly pin is gold over sterling. The wings are curved in arcs. The decorative enamel work in green and brown is exquisitely detailed; the maker is Hroar Prydz of Oslo, perhaps the best enamel worker in Norway. The pin has a safety catch and tube hinge, a combination of fittings indicating some age. This pin is 2" across X 1 1/8" tall. It is in excellent original condition.
